2) How to navigate back and forth among various pages within the same wiki with say several pages (suppose I have added 5 pages in my wiki and I would like to navigate through those pages),Is there a way where all of those pages and the contents in those pages can be accessed from the content stubs of the Home Page.If so it would be very intuitive and helpful.

Hi Arya Dey. The page Help:New page should answer your first question. Since a wiki's pages have no specific order, it's not possible to navigate through them without creating any kind of links. But I think you may consider the page Special:AllPages to be useful. See Special:SpecialPages for a list of other useful special pages. Regards
